This is the modified version of the classic Gastric Bypass which involves splitting the stomach vertically and closing with staplers to shape the stomach like a sleeve, leaving rest of the stomach intact and connecting the 2 meters forward of small intestine to the new stomach in a single connection way. In this surgery, the food ingested moves from the new stomach to the small intestine, bypassing most of it and this slows the absorption of food along with the amount of food that can be eaten because of the size of the new stomach. 
The surgery is usually done like Laparoscopic surgery with the help of little incisions opened around the abdomen and the patient heals within a couple of days.

• If the patient’s BMI is 35 – 39.9 and has obesity related health problems such as; hypertension, high cholesterol, type II diabetes, sleep apnea and other diseases.
• Or, a BMI of over 40 but without having obesity related health problems..
• Patients with gastroesophageal reflux or hernia in their diaphragm.
• Diabetes patients with a BMI lower than 50
• Sugar addicts with a BMI lower than 50

This procedure is not suitable for patients on these conditions:
• If the status of the patient is not fit for a surgery,
• If the patient has serious psychological disorders,
• If using general anesthetic is not possible,
• If the patient is pregnant,
• If the patient has alcohol or drug addiction,
• If there is an untreatable ulcer in patient’s stomach,
• If the patient has anemia or Crohn disease.

Weight loss amount changes from patient to patient or most importantly, regarding to diet or activity. Ideally, the weight loss expected after the surgery is listed below:
• 8 months later loss of %70 of excess weight
• 12 months later : loss of %85 of excess weight

• Observable improvement in reduction or healing diseases related to obesity such as diabetes, hypertension, cholesterol or sleep apnea,
• Better life quality: A lot patients feel a significant improvement on their quality of life,
• Increase in confidence after losing excess weight.

1. Anesthesia expert gives the patient general anesthetic
2. Just like in all Laparoscopic surgeries, the abdomen gets inflated by carbon dioxide with a needle that enters from the incisions made on the abdomen to make some room.
3. With the help of a wire, an endoscope that is connected to a monitor that visualizes intestines, stomach and other organs gets inserted from a few holes.
4. Surgical forceps and cautery along with other surgical equipment gets inserted.
5. The stomach gets freed from surrounding fat tissue.
6. In order to create a new stomach, upper part of the stomach gets cut off.
7. The upper part of the intestines gets skipped and the rest gets connected to the smaller stomach.

Since Laparoscopic surgery is done, the healing process is shorter than conventional surgery. Usually, the patient needs to stay at the hospital for two to three days and after two or three weeks, the patient can return to work. In four to six weeks, full recovery is made

Just like in all surgical procedures, there is a possible risk of complications. Generally the complication possibility of Gastric Bypass surgery is between %2-3 and includes:

• Leakage risk in new connection locations on stomach and intestines (1-3% probability)
• Bleeding in digestive system
• Blockage in digestive system
• Infection or sepsis of the wound
• Nausea and vomiting.
• Few patients face abdominal discomfort and nausea after surgery. This happens because the patient being in the adaptation period of the new diet and food habits. This discomfort can easily solved by visiting a dietician.
• Dryness: It is important to consume approximately 2 liters of water or liquid food a day for a few months during the swift weight loss because of the surgery and it may be difficult for the patient to consume that much liquid in the first few weeks after surgery. However when the patient adapts to this new diet, the difficulties slowly go away.
• Atelectasive pneumonia
• Deep vein thrombosis
• Pulmonary embolism

• Regaining of lost weight or reduced weight loss
• Gastric enlargement
• Peripheral ulcers
• Esophagus enlargement
• Dumping syndrome
• Small intestine blockage due to internal hernia or sticking
• Iron and vitamin deficiency
• Protein based lack of nutrition
• Anemia
• Neuropathy
• Osteoporosis
• Vitamin and mineral deficiency
• Kidney and gall bladder stones
• Depression
• Hair loss

• Great similar results in regards to the classic Gastric Bypass surgery for weight loss.
• It is considerably safer and easier than classic Gastric Bypass surgery and is also done in shorter amount of time. Since it doesn’t involve in as much intestine connection as classic Gastric Bypass, it has reduced complication probability theoretically.
• It shows great success in treating diseases like related to obesity
• Great success rate in regards to the treatment of diseases connected to obesity, especially diabetes, pressure and high cholesterol. Particularly, in type II diabetes, postoperative healing success levels are %95 in one year.

• Since some of the stomach is removed permanently, it can be considered as an irreversible process
• Serious acid reflux risk due to small stomach volume
• Change in the digestive system structure
